IMPROVEMENT IN SEWING-MACHINES.

Specification forming part of Letters Patent No. 168,894., dated October19, 1875; application filed August 21, 1875.

To all whom it may concern:

Be it known that we, JOSIAH GLINEs and NOEL W. STILEs, of Postsville,Allamakee county, Iowa, have invented new and useful Improvements onSewing-Machines, of which the following is a specification Our inventionconsists of a shuttle-carrier mounted on a pair of cranks, and operatedby a crank on the driving-shaft in such a manner that the shuttletravels in a true circle without revolving on its own axis, and thusdoes not twist the thread. I

Figure 1 is a side elevation of our improved shuttle motion; Fig. 2 isan end elevation, and Fig. 3 is an elevation of the shuttle-carrler.

Similar letters of reference indicate corresponding parts.

A is the shuttle-carrier, which is attached to the bar B, which ismounted on the cranks O, pivoted on support D hanging from the underside of the plate E, and the bar is geared with the crank F of thedriving-shaft Gr, having the same throw as the cranks O, and

swinging the carrier in a circular orbit with out revolving it, thusavoiding the twisting of the thread, and also saving friction bycarryingit altogether on pivots; and it also prevents noise. The shuttle H isgrooved a little in the sides I, and the flanges K, by which it isconnected to the carrier, are a little undercut or dovetailed to securethe shuttle when confined by the spring-latch J, so as not to require aface-plate along the circle around which the shuttle travels. L is theneedle baokingplate, along which the shuttle runs when passing theneedle.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- The combination,with a shuttle-carrier, of barB, cranks O O, and the crank F, and shaft G, as and for the purposespecified.
